Patented Nov. 7, 19.22.,

. ,3 arm TIRE-TUBIl-REP "Be itlmown that I, Gnonenl5. vVooD, a citizen of the United States, and reslding at Detroit in the county of iVa-yne and State of Michigan, have invented a new and Improved Tire-Tube-Repairing Kit, of which the following is a specification.

The presentinvention relates to a kit for repairing tire tubes and is an improvement on that disclosed and claimed in my U. S. Letters Patent No. 1,281,469, granted @ctober 15, 1918.

In the use of such kits, it is necessary that the soapstone or other foreign matter which ordinarily clings to the surface of the tire be removed around the cut or tear in order to secure a fresh and clean rubber area for the application of the cement. This may be done by the use of a rag wet in gasoline but the clothing of the user is often soiled thereby, and the operation is otherwise unsatisfactory. Moreover, the wet rag is usually either thrown away after using or inserted in the can, the net result being that the rag is either often missing when most needed or is pressed against the inner container and tends to soak off the abrasive with which one end of the latteris prefer ably covered.

In accordance with the present invention, the can cover is provided on its inner face with a pad of compressed felt or the like which may be used, when the cover is taken off and firmly grasped in the hand after the pad has been saturated, as an effective implement for rubbing and cleaning the rubber. The cover itself is preferably of tin and presents a relatively sharp edge with which the rubber may be further worked upon or scraped to expose fresh rubber sur faces and to remove foreign matter.

The invention is also concerned. with an improved assembly of the inner container and the clamp within the can, whereby the former is keptv away from the pad.

Again, the invention consists in certain improvements in the clamp whereby a more uniform gripping off the tire is attained.

In the drawing, Fig. 1 is a central longitudinal section showing one embodiment of the invention. Fig. 2 is a perspective view showing the manner of holding and working on the tire. Figs. 3 and t are perspective views of the dam: and the inner container respectively. Fig. 5 is an end view or: the clamp.

package as sold'includes an 1 and an inner container 2 A rab y being cylindrical paper These cans have covers 3 and a, re-

the iormer being of tin or the .raferably of the screw threaded There considerable difference in 'ieter oi the cans, which provides or a clamp 5. Within the inner contamer a roll of patch material 8 and a can of cement 9. One end of the can 2 is preferably coated with glue and dipped into emery dust to form an abrasive outer surface 10,

Various forms of clamps may be used but i prefer that shown, which is formed from nrdc piece of sprin wire bent to form pping portions or jaws l2 and 13 oined by a loop whereby they are normally held apart from each other, The gripping portions are of a length exceeding the diameter of the tire tubes, and the portion 12 is offset near its end to form a keeper or seat 15 into which the end of the portion 13 is received when the clamp is closed.

Tl clamp differs from that shown in my patent above referred to substantially only in that the loop 14; is in this instance bent into a plane an angle to the plane determined by the jaws. The change is of great ctical importance, however, as a much u are uniform gripping of the tire and much greater ease of manipulation is thus secured; other words, the previous clamp was relatively stilt and exhibited a tendency to grip the tire with a considerably greater pressure the points where the jaws merge into the loop la than elsewhere, which was due to the fact that the jaws necessarily flexed about the mid-point of the loop, whereas in the present case the jaws may be said to tie or have angular movement relative to one another about an imaginary point in their own plane beyond the midpoint of the loop.

Attached to the cover 3 on the inner side thereof in any suitable manner, as by means of a screw 17 or a coating of shellac, is a pad or swab 18, preferably formed of compressed felt.

l i hen cut or blow out is to be repaired, the contents of the outer container are removed and the tire is clamped in looped form about the latter, as shown in Fig. 2, the cut appearing at 19. The cover 3 is then end of the jaw 12 comes between the pad and the inner container the latter is kept free from the injurious effects the gasoline might otherwise have thereon.

Various changes other than those indicated may obviously be made without departing from the spirit of my invention; I

do not, therefore, wish to be limited except as indicated by the subjoined claim.

I claim:

A tire tube repairing kit comprising an outer cylindrical container having a detachable cover, a pad of fibrous material secured to the cover on the inner side thereof, a second cylindrical container within the first and adapted to contain tire patches, a clamp for securing a tire tube looped about the outer container, said clamp being adapted to be inserted in the outer container and having a ortion arranged to extend between the pad and the inner container to space the latter from the former.
